An aqueous solution of sodium sulfate is allowed to react with an aqueous solution of calciumnitrate. the complete ionic equation contains which of the following species (when balanced in stan-dard form)? a.2na+aq)b.2so42-(aq)c.3ca2+(aq)d. no3-(aq)e. k+(aq)

Answer : The correct option is, (a)

Explanation :

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced molecular equation will be,

The complete ionic equation in separated aqueous solution will be,

In this equation the species present are, are the spectator ions.

Hence, the complete ionic equation contains specie is

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

did anyone actually do this? like if anyone has submitted this i rly need .
